One mole contains 6.022 × 10²³ particles — if a mole of seconds passed, it'd be 19 quadrillion years.

A sheet is placed on a horizontal surface in front of a strong magnetic pole. A force is needed to: Hold the sheet there if it is magnetic. Hold the sheet there if it is non-magnetic. Move the sheet away from the pole with uniform velocity if it is conducting. Move the sheet away from the pole with uniform velocity if it is both, non-conducting and non-polar.Choose the correct statement(s) from the options given below:
A, C and D only
C only
B and D only
A and C only
To solve this problem, we need to analyze the behavior of a sheet placed in front of a strong magnetic pole.Let's evaluate each option:• Option A: Hold the sheet there if it is magnetic.A magnetic sheet will experience a force due to the magnetic field. This force will either attract or repel the sheet, depending on the orientation of its magnetic domains. Therefore, a force is needed to hold the sheet in place.• Option B: Hold the sheet there if it is non-magnetic.A non-magnetic sheet will not interact with the magnetic field, so no force is needed to hold it in place.
